Okay, so imagine you are playing with Legos. You want to build a castle, but you don't know how to start. So, you ask your friend for help.
Your friend tells you: "First, you need to build the walls. Then, you can add the towers. Finally, you can put the roof on top."
These are the production rules for building a castle. They tell you the steps you need to follow in order to build your castle.
In computer programming, we use production rules to tell a computer what to do. These rules are written in a special language that the computer can understand.
For example, let's say we want to teach a computer how to make a sandwich. We would write the production rules like this:
IF you have bread AND you have peanut butter AND you have jelly THEN make a peanut butter and jelly sandwich.
This tells the computer the steps it needs to follow in order to make a sandwich. It needs to check if we have all the ingredients, and then it can make the sandwich.
So, production rule representation is the process of writing these rules in a language that the computer can understand. It's like giving the computer a recipe to follow.
